鄂尔多斯地区成矿系列与地质建造的关系探讨

摘要

以往成矿系列概念以地质成矿作用为基础，为了使成矿系列理论既便于同成矿地质背景研究相衔接，又容易应用于矿产预测及找矿勘查，按照地质建造与成矿的相对时间，将与各类地质建造有关的成矿系列细化为同生成矿系列、准同生成矿系列、后生成矿系列等类别。借鉴已有的矿床成矿系列，运用新的理念，在鄂尔多斯地区划分的3个成矿区带的基础上，对该地区的矿床成矿系列进行了深化研究，初步确定了18个成矿系列，与11种地质建造有关。%Geological mineralization used to be the basis of the metallogenic series concept.To connect with the geological background studies and facilitate mineral forecast and prospecting, the research on the metallogenic series was conducted according to the relative period of geological formation and mineralization.Various metallogenic series related to geological formation were di-vided into syngenetic,penecontemporaneous and epigenetic series.With reference of pre-existing deposit metallogenic series,on the basis of three metallogenic belts,the main minerogenetic se-ries of mineral deposit in Ordos were studied,and 18 series related with 1 1 kinds of geological formation were identified.
